JOHN H. TUROOTTE, OF SPRINGFIELD, MASSACHUSETTS,

RING- CUTTER.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed March 9, 1908. Serial No. 419,862.

To all whom it may concern:

Be it known that 1, JOHN H. TURooTTE, a subject of the King of GreatBritain, residin at Sprin field, in the county of Hampden an Stateofdflassachusetts, have invented a new and useful Ring Cutter, of whichthe followin is a specification.

y invention relates to improvements in devices for cutting thread, yarn,twine, cord, etc., in which a ring having one or both edges slotted orindented to afford cutting means is em loyed.

his device is particularly useful for mill operatives who have to dowith thread or yarn of any kind or grade in the textile art, since itenables them to dispense with the knife commonly'used in connection withthe t ing of broken ends and for cutting single threads; it is alsouseful for the store and home in cutting string, twine, and cord. In themill the operative with the knife in his hand is very liable to cuthimself and also to injure the bobbins, spools, tube or cops which areunder his care, but with my ring cutter he is unable to cut the threador yarn on the bobbin, spool, tube or cop, where it never should be out,or to injure himself; he can, however, cut said thread or yarn at adistance from the. member upon which it is wound and out it to the bestadvanta e, and so close to the knot, in the event that t ere be a knot,

that there will be no ends left to produce a defect in the fabricsubsequently made from such thread or yarn.

The ob'ect of my invention is to provide a small, ligl it, simple,durable, and inexpensive device, adapted to fit any finger and even thethumb, whlch is capable of serving as a substitute for a knife or otherimplement in cutting thread, yarn, twine, string, etc. the same beingconvenient and safe at all times and under all conditions. I attain thisobject by the means illustrated in the accompanying drawings, in whichFigure 1 is a view showin one method of using my cutter; Fig. 2, a p anview of said cutter, and, Fig. 3, a side view of the same.

Similar fi res refer to similar parts throu hout t e several views.

While the device must be generally of ring shape or formation so as tofit the finger, i1 is obvious that it may have an exterior shape orformation which departs more or less from annularity, and it is to beunderstood that I do not restrict m self to the size or shape of thering or of the s ots therein nor to the number of the latter shown inthe drawings, since I have therein illustrated the embodiment of oneform only, although the preferred form so far as my experience teachesme at this time, of my invention.

Referring to the drawings it will be observed that I have therein shownasimple ring 5 having a plurality of transverse slots 6 in each edge.The slots 6 in each edge of the ring 5 are preferably equi-distant fromeach other, and those in one edge may be larger or coarser than those inthe other edge. Each slot 6 is under-cut and is in the form of a Veryacute or sharp a le, and it is usually at the outer end of the s ot andin the oint of the angle at this end that the actua cutting operationoccurs when a drawing pull is given a thread, for example, which hasbeen engaged with the ring at said point (see Fig. 1 wherein the threadis re resented at 7), although it is possible to pc orm such operationat the inner end of the slot. This last is seldom done on account of theinconvenience, hence there would be little or no object in extending theslots clear through to the o ening in the ring were it not for the factt at less work and ex ense are involved in the manufacture of the eviceby so doing.

The large number of slots 6 in the rin 5 1s the factor which insures thereadiness 0 said ring for instant use without re uirin to be turned orotherwise mani ulate all this is a very valuable feature 0 my invention.A further advantage in having many slots in the ring is found in theconsequent increase in length of time of efficiency as a cutting mediumcompared to a ring having a single slot or at best only a few slots.

The range of usefulness of the ring is enlarged in a way by providingsuch ring with two or more sizes of slots, but at the expense of thefacility with which the rin used without such variation in t e slots;therefore, except when the rin is to be infrequently employed as in t ehome and possibly the store it is better to have all of the slots in aring of the same size, as will be readily seen. i

What I claim as m invention, and desire to secure by Letters atent, is-

1. As a new article of manufacture, a ring adapted to fit a digitalmember and having an indentation in its. peri hery which indentationextends into one ed e without cutting into the other edge of saif ring,for the purpose set forth.

can be 2. As a new article of manufacture, a ring adapted to fit adigital member and having a plurality of transverse slots in the edgesof said ring, for the purpose set forth.

3. As a new article of manufacture, a ring adapted to fit a digitalmember and having a plurality of transverse undercut slots in the edgesof said ring, for the purpose set forth.

- 4. As a new article of manufacture, a ring adapted t0 fit a di italmember and having 10 transverse slots of ifferent sizes in the edges ofsaid ring, for the u ose set forth.
